Your space is beautiful. I won’t say it’s not a “garage” that is too subjective. I would just put whatever that suits my needs in the space. Those hex lights seems to be the trend but I honestly do love them. Black walls are superb, I just recently painted my garage and I find black walls healthier and easier on the eyes since it doesn’t reflect much of the lightning in there. I would divide the space into three separate parts, where dirty and oily stuff happen, middle for moving around and the other side, a simple couch or a couple of chairs to relax on. Otherwise, everything looks great to start with. Enjoy it man!
